What Is the Turning Moment on a Crankshaft?

TL;DR

The turning moment on a crankshaft is generated by the crank effort, which is the net force applied at the crank pin. It can be calculated using the equation ft * r * sin(theta + beta) / (2 * sqrt(n^2 - sin^2(theta))), where ft is the tangential force, r is the crank length, and theta and beta are angles related to the crank and connecting rod.

Transcript

hello everyone in this video we'll discuss about turning moment on crankshaft so we have already done the engine force analysis and we have discussed about the crank effort where crank effort is the this crank effort is what it is the force the net force which is applied at the crank pin and it provides the required turning moment on the crankshaft...

Key Insights

• 😴 The turning moment on a crankshaft is caused by the crank effort, which is the net force applied at the crank pin.
• 😴 The tangential force at the crank pin provides the turning moment and tries to rotate the crank about its fixed end.
• 💝 The value of the turning moment can be calculated using the equation ft * r * sin(theta + beta) / (2 * sqrt(n^2 - sin^2(theta))).
• 🔺 The exterior angle of the triangle is important in determining the perpendicular distance (or) for the turning moment.

Summary & Key Takeaways

• The turning moment on a crankshaft is generated by the crank effort, which is the net force applied at the crank pin.

• The tangential force at the crank pin, known as the crank effort, provides the turning moment to the crankshaft.

• The value of the turning moment can be calculated using the equation ft * r * sin(theta + beta) / (2 * sqrt(n^2 - sin^2(theta))).
